UPDATE: THE man captured on film allegedly carjacking a Sunshine Coast news cameraman after pointing a gun at him, before crashing the stolen Seven News vehicle into LPG gas tanks at a Doonan service station yesterday has been remanded in custody.

Jordy Brook did not appear in Maroochydore Magistrates Court this morning, facing four charges including one count of attempted murder, as his legal representative sought an adjournment on all matters.

No bail application was lodged, as his matters were adjourned to Tuesday, December 16, when Mr Brook was expected to appear via videolink.

EARLIER: IT TOOK only a matter of seconds for a man to change from a "nice guy" into a gun-wielding car thief, said a Sunshine Coast news cameraman, who stared down the barrel of the gun.

Just a few hours before the chilling scene was captured on camera, a man allegedly assaulted a woman in her 40s at a home in Wyandra St.

He fled the scene on his motorcycle, before allegedly waving down Seven News cameraman Peter Steer who was en route to the breaking story.

Mr Steer said the gunman initially appeared to be a "good guy" who just wanted his story heard.

"He handed me the pistol... he wanted to give himself up to police," Mr Steer said in a television interview yesterday morning.

"I got out of the car and phoned police. We were talking.

"He seemed agitated and quite upset about what had happened before. Next thing I knew he had gone from being 'Mr Nice Guy' to someone who was going to take my car. He picked up the pistol and pointed it at me."

A man was caught on video asking Mr Steer if he could call his mum after asking to turn himself in. The man fled in the news channel's vehicle.

Mr Steer was picked up by police and continued to film watching on as the man crashed the stolen car into gas cylinders at the United Petroleum service station, causing them to leak.

The area was cordoned off and declared an exclusion zone for most of yesterday.

Amid the chaos, a 36-year-old pregnant woman went into labour. Paramedics and the woman's husband had to be let past the incredibly strict 400m exclusion zone at Eumundi-Noosa Rd about 11.30am. The woman was transported to Nambour General Hospital for a caesarean.

Witness 'Joe' told ABC radio after the man crashed the car he got out and demanded a cigarette lighter or a light from a man at the service station.

He apparently intended to blow up either the gas cylinders or the service station itself.

The bystander ran to the service station and asked them to lock it up as they were in danger.

The offender was seen banging his head on the glass doors of the complex.

Joe said about six police arrived shortly after armed with guns which were pointed at the man before he was taken into custody.

Doonan's Cavan Herron, 33, said he saw the offender talking to Mr Steer minutes before the gunman turned on him and stole the car.

"I thought it was a cop car and they had pulled over a bikie," he said. "But then I saw someone with a video camera and thought 'cool bike, he must be doing a documentary'. They looked really casual."

A 45-year-old Noosa Heads man has been charged with attempted murder.

The man, who is accused of stealing a news cameraman's vehicle while armed with a replica rifle, has also been charged with unlawful possession of a firearm with an intent to commit an indictable offence, robbery while armed and wilful damage.
